# Setup When using spies, `sls-jest` sometimes needs to create temporary files to deploy and keep track of some underlying infrastructure they require to function. Those files are not meant to be committed to your repository. Consider adding `.sls-jest` to your `.gitignore` file. In order to keep track of the different stacks across different users/branches/environments, etc. you also need to specify an environment variable named `SLS_JEST_TAG` before running `jest`. ```bash export SLS_JEST_TAG my-branch ``` ## Cleaning up When you are done with your tests, you can clean up any remaining architecture and artifacts using the following command: ```bash npx sls-jest destroy -t my-branch ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://serverlessguru.gitbook.io/sls-jest/spies/setup.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
